• Accelerated Impact of Climate Change on Human Wellbeing, Nature

    Increased heatwaves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals. These weather extremes are occurring simultaneously, causing cascading impacts that are increasingly difficult to manage. They have exposed millions of people to acute food and water insecurity.

  • Improving Bay Area Seismic Hazard Maps

    Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for the first time. The findings may be used to improve seismic hazard maps of the Bay Area.

  • Lake Evaporation Patterns Will Shift with Climate Change

    Lakes serve as a major global source of freshwater. As temperatures continue to get warmer, so will lakes. As global average temperatures rise, lake evaporation is projected to increase at double the rate of ocean evaporation. However, future increases in lake evaporation vary substantially across regions.

  • How a Two-century Megadrought Gap Set Up the West for Its Water and Climate Crisis

    Since the turn of the 21st century, researchers probing evidence locked in tree rings and other clues to past climate conditions have been building an increasingly unnerving picture of southwestern North America as prone to deep, prolonged droughts. Megadrought is the emerging term for the worst of these extreme dry spells — those lasting two decades or more.

  • Hotter, Drier Nights Mean More Runaway Fires

    Thanks to the warming climate, the potential for more severe nighttime wildfires is increasing, and warmer nights mean firefighters will not be able to rely on cooler temperatures to help them get a handle on fires, a new study shows.

  • What Drives Sea Level Rise? U.S. Report Warns of 1-Foot Rise within Three Decades and More Frequent Flooding

    Sea levels are rising, and that will bring profound flood risks to large parts of the Gulf and Atlantic coasts over the next three decades. A new report led by scientists at the National Oceanic and Atmospheric Administration warns that the U.S. should prepare for 10-12 inches of relative sea level rise on average in the next 30 years. That much sea level rise means cities like Miami that see nuisance flooding during high tides today will experience more damaging floods by midcentury.

  • U.S. Coastline to See Up to a Foot of Sea Level Rise by 2050

    The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That’s according to a NOAA-led report updating sea level rise decision-support information for the U.S. The report also finds that the sea level rise expected by 2050 will create a profound increase in the frequency of coastal flooding, even in the absence of storms or heavy rainfall.

  • Co-Occurring Droughts May Threaten Global Food Security

    Droughts occurring at the same time across different regions of the planet could place an unprecedented strain on the global agricultural system and threaten the water security of millions of people, according to a new study.

  • Ripple Effect: Lessons from the Tonga Eruption

    An eruption of the Hunga Tonga-Hunga Ha’apai volcano in the South Pacific Ocean on January 15, 2022 created a rare event never before detected with modern instruments. A powerful tsunami raced forward, leaving an untold number of lives hanging in the balance.

  • Identifying “Double-Hazard” Zones for Wildfire in the West

    Rapidly growing communities in the American West’s forests and shrublands are nestled in zones where local soil and plant traits amplify the effect of climate change on wildfire hazards and lead to bigger burns.

  • Survivors of Weather-Related Disasters May Suffer Accelerated Aging

    What is the toll on the long-term health of the population of the stress caused by major natural disasters? And could exposure to extreme weather events accelerate the aging process? A new study offers sobering insights.

  • Disaster News on TV and Social Media Can Trigger Post-Traumatic Stress in Kids Thousands of Miles Away – Here’s Why Some Are More Vulnerable

    Natural disasters are typically accompanied by a flood of gruesome images on TV and social media. These images can have a powerful psychological impact on children – whether those children are physically in the line of danger or watching from thousands of miles away.

  • U.S. Army Releases Its Climate Strategy

    The U.S. Army announces the release of its first Climate Strategy that guides decision making in response to threats from climate that affect installation and unit sustainability, readiness, and resilience. The strategy directs how the Army will maintain its strategic advantage through deliberate efforts to reduce future climate impacts and risks to readiness and national security.

  • Disaster Expert Testifies in Congress Regarding Future Pandemics

    “The severity, the disruptions, the politicization of the response, the inequities, and the pandemics’ persistence were all predicted in various reports, studies, and historical records of prior pandemics. The shortage of ventilators, personal protective equipment, and healthcare system capacity was the subject of numerous reports, including from the federal government…. We didn’t want to spend the money on what was needed, so we are dealing with the consequences now. And our response is a lot more expensive and a lot less effective as a result”: Colombia University’s Jeffrey Schlegelmilch.

  • When Water Is Coming from All Sides

    When hurricanes hit, it is not solely the storm surge from the Gulf of Mexico and Atlantic Ocean that led to flooding. Inland sources, like rain-swollen rivers, lakes and suburban culverts, also contributed significantly. Researchers have developed and tested the world’s first 3D operational storm surge model, which takes these factors, which were missed by many computer models at the time, into account.
